To all'w'hom it may concern:

Be it known that I, MERIAN H. DICKIN- SON, a citizen of the United States, residing at Seattle, in the county of King and State of \Vashington, have invented certain new and useful Improvements in Hoisting and Conveyin Means, of which the following isa specification.

My invention relates to new and useful improvements in hoisting and conveying means, and more particularly to drum engines for operating the lines of hoisting ap-v paratus and cable ways.

The invention consists in the improvements and combination of parts to be fully described hereinafter, and the novelty of which will be particularly pointed out and distinctly claimed.

I have fully and clearly illustrated my invention in the accompanying drawings to be taken as a part of this specification and wherein: Figure l is a plan view, partly in horizontal section, of the drum portion of the hoisting and conveying engine. Fig. 2 is a; view in side elevation of the structure shown in Fig. 1.

Mounted in suitable bearings in parallel side frames18, which are spaced apart from each other, is a horizontally-disposed power shaft 19, carrying on its opposite ends crank disks 20, connected by pitmen 21-, with the piston rods 22, of the power-cylinders 23, of a steam en ine, whereby said power shaft is driven in he direction of the arrow, as shown in Fig. 3. Keyed to the power shaft 19, is a driving pinion 24, which meshes with-a large drivinggea'r 25, which is keyed to a drum-shaft 26 journaled in bearings 27 on the side frames 18, said shaft 26 running parallel to the said power shaft 19. This shaft 26 carries the inhaul drum 12, heretofore mentioned, which is arranged to revolve freely on said shaft independent of the latter and to have movement longitudinally thereof toward and away from the gear 25, screw-thrust means 28, of well known construction, being preferably employed for efi'ecting said longitudinal movement of the drum 12. Friction clutch means is employed for connecting the drum 12, with the gear 25, which may consist of a friction clutch member 29, on the gear 25,- adapted to coiiperate with a friction clutch member 30, on the adjacent head of the Specification of Letters Patent.

drum, so that, when the drum is moved toward the gear 25, driving connection be tween the two will be made, while movement of said drum away from the gear will break the driving connection to permit the shaft 26, to revolve independently of the drum, or the drum torevolve free from the shaft.

The flange of the drum adjacent the gear2 5,

may be provided with a circumferential braking face 31, with which cooperates a band brake 32, in a well known manner.

frame members 18, and in advance of the; power shaft is a second drum-shaft 34, upon which is keyed a large driving gear 35, normally in mesh with the gear 25, heretofore" described, so that said gear 35, is driven" from the power shaft 19, through the pinion 24, and said gear 25. This shaft 34, carries the drum 17, heretofore mentioned, which is mounted on said shaft for revolution inde pendently thereof and for movement longitudinally of the shaft, said drum having end flanges 36, 37 the former of which is provided on its-face adjacent the gear 35,

with friction contact surface 38, to cooperate with friction blocks 39, carried by the gear35, whereby driving connection may be made between the gear 35, and the drum 17, to drive the latter in the opposite direction from the drum 12, when the latter is connected to its driving gear 25.

I provide improved means whereby the direction of revolution of the drum 17 may be reversed from that'just described without reversal of the driving shaft 19. This means preferably, although not necessarily,-

consists of a gear 40, keyed to the shaft 34, adjacent the flange 37, onsaid drumagd a larger internal gear '41, having its hub 42, rotatably mounted on the hub 40*, of the gear 40, as clearly shown in Fig. 2 of the drawings. Driving tween the gear 40, ahd the internal gear 41, by means of'a pinion 4:3 mounted on a stub shaft 44, journaled in a bearing 45, on one .of the side frames 18. The gear 11, is provided with friction clutch blocks 16, adapted to coiiperate with a friction clutch surface 47, on the outer face of the flange '37, of the drum 17. Thearrangement of the connection is made bee.

gears 35, and 41, with the respective clutch means between said gears and the flanges of the drum 17, is such that, when the drum is moved lengthwise of the shaft in one d1- 17, that, when the drums l2,
